Les Principes de la connaissance humaine sont l'occasion pour Berkeley de nier l'existence des idées générales abstraites. Il admet cependant l'existence d'idées générales, plus exactement d'idées déterminées à signification générale. C'est ainsi qu'il peut rendre compte de la généralité de certaines démonstrations. L'exemple choisi est celui de l'idée de triangle dans le cadre d'une démonstration géométrique. Mais peut-on également rendre compte de cette manière des démonstrations et des idées algébriques et notamment celle de quantité? In the Principles of human knowledge, (...) Berkeley clearly denies the existence of abstract general ideas. He assumes, however, the existence of general ideas or, more exactly, of determinate ideas with a general meaning. In this way, he explains the generality of certain demonstrations. He chooses the example of the idea of a triangle within a geometrical demonstration. But can he likewise account for algebraic demonstrations and ideas, and in particular for the idea of quantity? (shrink)

São variadas as interpretações da crítica berkeleyana às idéias abstratas, mas elas costumam concordar na tese de que essa crítica gira em torno da natureza das “idéias”. Isto é, se “idéia” for o mesmo que “imagem”, então a abstração lockeana é impossível, caso contrário, não. Neste artigo eu procuro mostrar que essa crítica não depende de idéia ser ou não uma imagem e que Locke está parcialmente consciente do problema levantado por Berkeley. Locke's general triangle and Berkeley's partial considerationThere are (...) many different interpretations of Berkeley's attack on abstract ideas, but they usually agree in sustaining that this attack depends on the nature of "ideas". That is, if "idea" is the same as "image", then lockean abstraction is impossible, but otherwise not. In this paper I show that this attack on abstract ideas does not depend on the issue concerning the nature of idea as image, and that Locke is partially aware of the problem raised by Berkeley.
